Private Identifiable Information

Understand Galileo's PII Metric

Definition: Identify PII spans within a sample (both input and output). The current model detects the following precisely defined categories:

• Account Information: account numbers, BIC and IBAN.

• Address: must contain at least a street name and number, and may contain extra elements such as city, zip code, state, etc.

• Credit Card: credit card number, CVV and expiration date.

• Date of Birth: must contain a day, month and year.

• Email.

• Name: must contain first and last name (and optionally middle name).

• Network Information: IPv4, IPv6 and MAC addresses.

• Personal Identification: personal IDs not included in other categories. In particular: PIN, IMEI, VIN, VRM, Driver license.

• Password.

• Phone Number.

• Social Security Number (SSN).

• Username.

Calculation: We leverage a Small Language Model (SML) trained on proprietary datasets.

Usefulness: Automatically identify PII occurrences in any part of the workflow (user input, chains, model output, etc), and respond accordingly by implementing guardrails or other preventative measures.

Explainability: To highlight which parts of the text were detected as PII, click on the 👁️ icon next to the PII metric value. The type of PII detected along with the model's confidence will be shown on the input or output text.
